After upgrading infrastructure, as described in the blog, default login account has changed to ec2-user. To administer the instance, I need to login as root but I can’t because I’m asked root’s password when trying to “su”, “sudo”, or “passwd”. Before upgrade, I only accessed with SSH key and hadn’t set password for root. How can I get root password? or Is there other way to login as root? ---

This is an option: [https://aws.amazon.com/articles/5213606968661598](https://aws.amazon.com/articles/5213606968661598) Unfortunately AWS will not, as far as I can find anyway (I’ve looked), let you modify the root user’s authorized\_keys file unless you SSH in and do it yourself. Instead the option above lets you build a new box, attach the old system’s disk to it, and then you can hack in your key and then move the old disk back to the old system and fire it up. Not hard, just take fifteen minutes or so. – Good luck. If you find this post helpful and are logged into the web interface, show your appreciation and click on the star below… ---

sudo -i should work, I am pretty certain that was tested.
